To all whom t may camera:

Be it known that I, FELIX RinsENiinnG, a citizen of the United States,and a resident of. Tuckahoe, in the county of I/Vestchester and State ofNew York, haveinvented a new and Improved Cordage Structure` of whichthe following is'a full, clear, and exact description. y

The present invention relates to new and useful improvements in cordage,and it. perf tains more particularly to a new and novel construction ofcover for strands.

It is one of the objects of the present invention to provide a cover forstrands in which the cover will withstand greater wear than covers ascommonly constructed.

It is a further object of the invention to construct the cover so thattheibers from which it is formed, will occupy 'a position in `whichtheir longitudinal axls will be more nearly parallel to the longitudinalaxis of the finished rope than is the case in rope as ordinarilyconstructedf v It is a further object of the invention to construct thecover so that a shorter length ofindividua'l fiber is presented to theabrasive action of wear in service, thereby increasing the life of therope.

It is a still further object of the invention to construct-the cover sothat a better hold or grip may be obtained, which greatly enliancesthe'v value of' the rope a-s a hand rope,

such. for'exarnple, as hawsers, heavy sheet ropes, me, v i

lVith the above and other objects in view, reference is had to theaccompanying drawings, in whichy Figure 1 is a view in elevationof arope constructed in accordance with the presentl ing partiallyunraveled, and

Fig. 2 is a transverse sectional -view taken on the line 2-2 of Fig. 1.p

In the usual manner of -making rope,.the strands are formed from anumber of yarns all ot the same kind, that is, yarns spun from fiber.Several of these yarnsare placed together to form the body of the rope,after which an outer layer of yarns is employed, the yarns of whichouter layer consists are known as cover yarns. These cover yarns in theusual method of manufacturing rope, are generally of the same size,shape, material and construction 'as the yarns invention, one of-thestrands of the'rope be;

lemployed in the body of the strand, and are laid spirally about thebody of the strand Application tiled April 24, .1923. Serial No.634,328.

In the drawings, the referencecharaeter 5 designates the rope, and suchrope is com?V posed of strands (i laid together. Each of these strandscomprises a body portion i, about which is spirally laid cover elements8.

As more clearly shown, each of these coverk elements S comprises twoyarns 9, which are twisted about each other or' laid as heretoforedescribed. By this construction it will be seen that the fibers oftheyarn's comprising the cover elements occupy a position substantiallyparallel to the longitudinal axis of the finished rope and that due tolayingv a.

plurality vof yarns'together to form a single cover element, arelatively short length ot' liber is presented to the action of Wearduring usage of the rope.

While in the present instance the body ot the strands is shown ascomprising two members laid together, it is to beunderstood thatv thebody of the strands may be a plurality of members either in twisted orun! twisted relation without departing from the 'spirit of theinvention, and, therefore, I do notv wish to be limited to the two-partbody construction shown in the drawings. I

VVh-at is claimed is:

A rope comprising a plurality of strands, twisted together 1n one andthe san'iedlrecf` tion, each strand comprising a core etelements'twist-ed together in a twist opposite to` the twist of saidstrands, and a covering for each core, said covering comprisingelement-s 101,

twisted together in a twistsimilar to the twist `of the elements olfsaid corre, the ele'- ments of Leach core constituted of fibers twistedtogether in Va twist opposite to the twist of .the elements of the core,the' elements 0f the'coveriug constituted (if-yarns twisted together ina twist opposite to the` twist of the elements of said covering, andsaid yarns constituted of fibers twisted t"ogether in a twist oppositeto the 'twist of said yarns.
